KFC shocking customer service

3 weeks ago I ordered food on the KFC App. The payment went off my card but the order did not go through.

I reported this to KFC customer service, I was told a refund will be done within 72 hours. I sent twice proof of payment.

Three weeks later still no refund, in between I have sent emails and phone calls to follow up on my little refund of R120.

I am highly disappointed in your Customer Service.

Is this how you treat your Customers?
